Part of Pennsylvania Turnpike closed this weekend for bridge removal

PITTSBURGH — A section of the Pennsylvania turnpike will be closed for five hours Saturday into Sunday so crews can remove a bridge.

Starting 11:59 p.m. Saturday through 6 a.m. on Sunday, the turnpike will be closed from the Allegheny Valley exit to the Pittsburgh exit.

During the closure, crews will remove the original Unity Trestle Road bridge which carried traffic over the Turnpike at milepost 52.36 in Plum Borough.
